How can I get my Solaris 11 system to
respond
to two different IP addresses on the same interface?

ANSWER

Each device on an IP
based
ethernet should have a name. Since your workstation
is going to be
(in effect) TWO devices, you need to choose a second
name. That second
name needs to be added to the file /etc/hosts on the system, AND to the database on
any name
service systems that will include it in their
domain, for example DNS.Example.
If you have a system known as "herring" which responds to the IP address 192.9.200.47, and you also want it to respond to 155.134.44.17 as "jupiter", the you
will ensure that you have both the following lines
in /etc/hosts (and/or DNS):

192.9.200.47 herring155.134.44.17 jupiter

You now need to choose
which
ethernet interface the second address will be used
on.

If it will be used
on the
SAME interface that you already use (for "herring") in our example, then you run the
ipadm command to
bring the second name into use, as follows:

ipadm create-addr -T static -a 155.134.44.17/16
net0/v416(in this example, the default
interface has the name "net0")

At this point your system is
responding to
the second IP address, and this configuration will
persist across a reboot.
